According to http://www.xmpp.org/specs/rfc3921.html#def / Section B5 // -- <?xml version='1.0' encoding='UTF-8'?> <xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema' targetNamespace='jabber:iq:roster' xmlns='jabber:iq:roster' elementFormDefault='qualified'> <!-- ... --> <xs:element name='item'> <xs:complexType> <!-- .. --> <xs:attribute name='name' type='xs:string' use='optional'/> <!-- .. --> </xs:complexType> </xs:element> <!-- .. --> </xs:schema> // -- The "name" attribute of the "item" element in "jabber:iq:roster" namespace is optional. What I personally understand from this: a) items can have no "name" (nickname) - when "name" is missing b) items can have a "name" (nickname) - when "name" is present Therefore, when you give/receive "name" that means the item has some nickname set, no matter what the contents of "name" is. Under these conditions, a client receiving name='' should list a blank space in the roster - which is not something you'd like, I think. IMO, missing "name" is not the same with empty "name". I would go with method 1. Regards, Mircea -- http://mircea.bardac.net
